Recent Trends on UAS-UTM Ecosystem and Integration Challenges

Unmanned traffic management (UTM) is a critical component in the integration of unmanned aircraft systems (UAS) into the national airspace. As UAS operations continue to grow in scale and complexity, the development of a robust UTM ecosystem becomes essential to ensure the safety and security of the airspace. This survey aims to explore the current state of UTM technology, policies, and procedures, as well as the challenges and opportunities facing the UTM ecosystem. It will review the existing UTM architectures and frameworks, such as those developed by the Federal Aviation Administration (FAA) and the European Union's U-space initiative (U-SPACE), and evaluate their effectiveness in managing UAS operations. Furthermore, it will also examine the key UTM service providers and their offerings, including UAS traffic management systems (UTM systems), communication and navigation systems, and airspace management services. Additionally, it will explore the role of government agencies, UAS operators, and technology providers in the development and implementation of UTM solutions. At last, the author of this paper discuss V2X communication threats related to UTM. By providing a comprehensive overview of the current state of UTM, this study will contribute to a better understanding of the challenges and opportunities in the UTM ecosystem and inform the development of future UTM solutions.
